What is RBAC (Role-Based Access Control)?

An access control model where permissions are assigned to roles, and users are assigned to roles rather than getting permissions directly.

RBAC simplifies permission management. Instead of assigning 50 permissions to each of 100 users, you create roles (Admin, Editor, Viewer) with appropriate permissions and assign users to roles. Changing a role updates all users with that role.

RBAC supports role hierarchies (Admin inherits Editor permissions), separation of duties (no single role has all power), and audit compliance. Most applications implement RBAC: database systems, cloud platforms (AWS IAM roles), and web frameworks.
